What types of surveillance cameras are there?

We could divide the current surveillance camera market into two types. We have just mentioned the so-called “analog” cameras, as well as the cameras with “IP” technology . If these terms don’t mean anything to you, don’t worry! In this section of our comparative guide, we explain in more detail the main characteristics of these devices, and the differences between them.

Analog cameras

  • Devices running on older technologies.
  • Generally reduced price, but at the expense of image quality.
  • The image is transmitted analog and initially measured in TV lines (TVL). However, newer models are now measured in pixels.
  • A video storage system and coaxial type cable are required for installation and operation.
  • Each function requires the use of a specific cable: one for audio, one for sound, and another for power. This can result in higher than desired costs.
  • A digital video recorder (DVR) is generally used, although sequencers or multiplexes can also be considered.

Digital or IP cameras

  • Intended to be viewed via the Internet, via a local network or a WiFi network.
  • Can operate wirelessly, via coaxial cable, or via UTP (twisted pair) cable.
  • Provide more viewing options, such as zooming, to make facial recognition and motion detection easier.
  • Storage method usually through an SD memory card or through a cloud service. A network video recorder (NVR) can however be used just as well.
  • Image resolution is much higher up to 1080P and videos in HD and even 4K in the most sophisticated models.
  • Installation made easy by the possibility of using a WiFi network. In the case of wired use, only one cable is required. It is used for power, video, audio and control at the same time.

Other Types of Surveillance Cameras

Security cameras can also be categorized by their design and shape:

  • Dome: The most popular model for home or small business use. They have a “dome” shape, with a lens in the center. Those that have a night vision function also have infrared LEDs incorporated around the lens.
  • Bullet: More elongated design, they are also very popular in homes and small businesses. They are generally suitable for outdoor use. Infrared LEDs surround its lens, located in the center.
  • Body: Elongated design, but this time rectangular in shape, with a separate lens on the front. These professional cameras are generally designed for larger businesses. Which lens to use with these cameras depends on the desired effect.
  • PTZ: Its initials stand for “Pan” (rotation), “Tilt” (tilt) and “Zoom” (approach). They are remotely controllable by means of remote controls. These cameras are intended for strictly professional and demanding use, such as that required by department stores, prisons, parks.

The criteria for buying a surveillance camera

You probably think that the function of a surveillance camera is limited to filming and sending an alert in the event of motion detection. You are not completely wrong! However, it is the way of carrying out these functions, and therefore the characteristics specific to each device, which vary. We explain some of the most redundant features in tests and comparisons below, so you can find the best surveillance camera for your needs.

Alerts and application

So that you do not have to be constantly vigilant, it is of paramount importance that your surveillance camera can send alerts to several of your control devices in the event of the detection of an anomaly or suspicious movements. In the event of an incident, this function will inform you instantly.

Some cameras include apps to monitor and control them remotely from your mobile device of choice or your computer. They have the advantage of giving live access to filmed images, on the sole condition that you have an Internet connection. In addition, these applications will allow you to benefit from useful functions, including pausing and activating recording, or changing the direction of the camera lenses.

Facial recognition

Constant technological progress has brought the most sophisticated cameras to the market, equipped with this very useful feature that is facial recognition. Through a program, the camera analyzes and compares segments of video, thereby identifying a person’s physical characteristics and facial features.

If the camera recognizes a person’s face, it does not trigger. The system will therefore not send any alert to the owner. If, on the contrary, the camera fails to identify the individual, it will alert you immediately.

The criteria for buying a surveillance camera

You probably think that the function of a surveillance camera is limited to filming and sending an alert in the event of motion detection. You are not completely wrong! However, it is the way of carrying out these functions, and therefore the characteristics specific to each device, which vary. We explain some of the most redundant features in tests and comparisons below, so you can find the best surveillance camera for your needs.

Alerts and application

So that you do not have to be constantly vigilant, it is of paramount importance that your surveillance camera can send alerts to several of your control devices in the event of the detection of an anomaly or suspicious movements. In the event of an incident, this function will inform you instantly.

Some cameras include apps to monitor and control them remotely from your mobile device of choice or your computer. They have the advantage of giving live access to filmed images, on the sole condition that you have an Internet connection. In addition, these applications will allow you to benefit from useful functions, including pausing and activating recording, or changing the direction of the camera lenses.

Facial recognition

Constant technological progress has brought the most sophisticated cameras to the market, equipped with this very useful feature that is facial recognition. Through a program, the camera analyzes and compares segments of video, thereby identifying a person’s physical characteristics and facial features.

If the camera recognizes a person’s face, it does not trigger. The system will therefore not send any alert to the owner. If, on the contrary, the camera fails to identify the individual, it will alert you immediately.

Did you know that the first CCTV system was designed by German engineer Walter Bruch in 1942, and was used to control V2 missiles during World War II?

Resolution and night vision

The image quality you want to have will be the main element determining the choice of a surveillance system. This is the criterion you should pay attention to when going to watch product reviews. The resolution of your camera is a very important factor in defining the quality of a CCTV system. With technological advances in the field, you will be able to find cameras with the ability to film in Full HD, and even in 4K. Keep in mind that the higher the resolution, the easier it will be to identify intruders and determine exactly what the camera is recording.

The technology used may, depending on the case, limit the resolution of the surveillance cameras . Indeed, the storage capacities of the recorder will directly determine the image quality. In some cases, archiving in the cloud may cause a drop in resolution, which is then limited to 720P. Conversely, cameras with local storage can take advantage of the maximum resolution, depending on their capacity.

Night vision is an essential feature when acquiring your equipment. Indeed, most crimes such as burglaries take place at night. Some cameras automatically switch to night mode when they perceive a drop in light, others have a timer that will allow you to set a specific time for the mode to be activated.

Viewing angles, tilt and rotation

For a satisfactory use of your camera, elements such as viewing angle, tilt and rotation are essential factors. They determine the amplitude and depth of the field of vision. Of course, this varies from model to model, with some offering a much wider field of vision than others.

A camera capable of rotation will cover a larger area. It can be controlled to direct it in a specific direction. Cameras operating via an application are then much more effective. In this case, your mobile device allows you to remotely control the movements of the lens.

We recommend for your camera a viewing angle of at least 130°, an almost full rotation angle of 355° and a tilt of 80°. In this way, you will benefit from an almost 360° vision offering a complete panorama.

Storage method

The advantage of local storage is that it allows recordings to be kept at high resolution when they are archived. It can be performed on an internal memory card, or even on a recording device. However, it has the disadvantage of not allowing the recovery of recorded data in the event of theft, loss or destruction of the camera.

Motion detectors

Another fundamental characteristic to take into account in YOUR choice, motion detection. It is by means of the detectors that your system will alert you in the event of unusual activity. In the event of the irruption of an individual in your home or any other crime, the system will inform you instantly.

Some more sophisticated camera models can tell the difference between people, animals and automobiles. The presence of this feature will depend on the range and sensitivity of the camera’s detector. The advantage here is to prevent the sending of unnecessary alerts to the user, in the event of the passage of an animal for example.

Two-way audio

We end with a last characteristic, which is not for all that less important. Although the main function of a surveillance camera is to record the image, there is no doubt that its coupling with the recording of sounds makes the system even more efficient. Thanks to the two-way audio function, no sound can escape you. The system will inform you of absolutely everything that happens in the monitored area.

In addition, cameras with the ability to record sounds will allow you to speak through the device, through a small speaker inserted into it. This is an undeniable asset for communicating with a family member present on site, or to intimidate and deter an intruder.

FAQs

How do security cameras work?

Several elements determine the operation of each camera and their specific use, in particular the type of camera, the recording mode (permanent or upon motion detection), and above all its storage medium. Simplifying, however, we could summarize their operation as follows: surveillance cameras send the images filmed to a central unit, responsible for storing them. If they are analog cameras or digital cameras with recorder, the central unit will then transmit them to a device such as a television, a monitor, or a computer. On the other hand, a so-called IP camera will allow it to send these images directly to a mobile device, such as your mobile phone or tablet.

What storage and recording methods exist for surveillance cameras?

We can distinguish 3 different storage methods by which it is possible to save the images filmed by your security camera. As we mentioned earlier, the type of camera (analog or digital) often defines the storage medium. The digital video recorder (DVR according to its English abbreviation) is used to record images from an analog surveillance system. A coaxial cable is required to connect the camera to the video recorder, which then sends the image to a monitor. This method converts the analog signal into a digital signal. In some cases, it is possible to connect them to the Internet and control the camera remotely. The network video recorder (NVR according to its English abbreviation) connects to the digital or IP camera by means of a UTP (twisted pair) network cable. We recommend this method for a camera that cannot accommodate an SD memory card and therefore does not need to convert the signal. Once connected to the network, the camera can be controlled remotely. The SD memory card is used exclusively for cameras that have a port to accommodate them. Generally, cameras support cards whose storage capacity is between 64 and 128GB. Local storage implies the obligation to empty the memory of the SD card once it is full. The absence of a cable and any additional system makes it very practical to use. It is also possible to keep the recording in a cloud.

For whom is the acquisition of a surveillance camera recommended?

Few shops and businesses are permanently occupied. These regular and prolonged absences therefore make them prime targets for burglars and other intruders. Therefore, surveillance cameras are essential devices to provide the owners of these establishments with better security. The user will be able to monitor customers or employees remotely at any time, and thus identify possible crimes. Moreover, these cameras are not just limited to monitoring and controlling your business. They are also very useful for domestic use, our homes being unfortunately subject to the same risks as businesses. Growing insecurity spurring demands for surveillance cameras, it is now possible to find cameras at very democratic prices. However, these may be suitable for basic use. In addition to providing better security for your home, surveillance cameras are also perfect for monitoring small children or pets. They allow you to stay vigilant at all times, from your mobile or tablet.

Are they really waterproof?

Yes, most brands of outdoor cameras are weather resistant as long as they meet international standards IP66 or IP67.

How do I determine how many surveillance cameras I will need?

The best way to determine how many cameras you need is to hire a professional. The objective being to cross the viewing angles, the number of useful cameras will depend on the number of places to be monitored.

Is it possible to record data without a hard disk in the recorder?

No, you will necessarily need a hard drive to record and view the videos.
